    05 - 134A Sequenced Radical Reaction - A Novel Stereocontrolled Route toAngularly Disubstituted cis-Decalins. The complete stereocontrolledsynthesis of angularly disubstituted cis- decalins is achieved based on sequencedradical ring expansion and cyclization of cyclopentanones (I) and (VII). Thestereochemistry of this radical reaction is discussed. The compounds preparedare of interest as potential intermediates for the synthesis of biologicallyimportant compounds.
